Finally I finished this new vector pack of army forces. I was trying to draw most useful poses and silhouettes: soldiers, infantry, the foot, FBI, SWAT, Special forces, special mission unit, anti-terrorist unit, riot police.
Vector images can be opened in many drawing program, for example: Xara, Corel Draw, Quark, PMView, Macromedia Freehand, and of course Any Adobe Software Indesign, Illustrator, Photoshop etc. can be used to open and edit vectors. Adobe Illustrator my certain decision! It is very simple to modify any vector illustration: recolor, replace shapes, add something new, change size, rotate.
